and neck of the femur are wanting at their normal place, and 

 :a flat surface on the femur indicates where the neck should 

 have joined it. The outer surface of the bone which fills 

 the acetabulum has evidently rubbed against the site of the 

 neck, for although the opposite surfaces are for the most part 

 porous, they each have patches of eburnation. There are no 

 appearances at the line of junction of the head and acetabulum 

 which would indicate anchylosis from arthritis deformans before 

 the fracture. 



For a comparatively recent example of a detached head 

 lying in the acetabulum, see K'o. 3. 184. G. C. 1849.

SHOULDER-JOINT. 



7. 183. Advancing- Arthritis Deformans of the Shoulder, 

 with Absorption of the Tendon of the Biceps. — 



Upper half of the right humerus of an old person, cleaned of 

 all soft parts, except some of those attached to the bicipital 

 groove, and dried, illustrating the above. 



The biceps tendon, at its upper end, is represented by a 

 hollow tube, attached to the upper part of the bicipital groove. 

 The articular surface seems fairly normal, but there is some 

 enlargement at the articular margin. G. C. 3477.

7. 184. Advancing" Arthritis Deformans of the Shoulder, 

 with Absorption of the Tendon of the Biceps. — 



Upper end of the left humerus of an old person, cleaned of 

 all soft parts, except those attached to the bicipital groove, 

 and dried, illustrating the above. 



The tendon of the biceps is somewhat diminished in size, 

 and has been adherent in front to the lesser tuberosity. There 

 is considerable irregularity round the articular margin of the 

 bone, especially at the upper part. G. C. 3477.
